· JVASP-42298· Li6FeO3F3

Li6FeO3F3 is an experimental lithium iron oxide-fluoride ceramic compound belonging to the family of mixed-anion lithium materials. This compound is primarily of research interest for energy storage and electrochemistry applications, where the combination of lithium, iron, and fluoride ions offers potential advantages in ionic conductivity and electrochemical stability compared to conventional oxide-only ceramics. The material remains largely in the development stage, with potential applications in solid-state battery electrolytes and ion-conducting ceramic membranes where its mixed-anion structure could provide enhanced lithium-ion transport pathways.
